I claim:

1. In a grease gun of the class described, a barrel having a nozzle at one end, a plunger rod projecting through the other end, plunger sections associated with said rod and barrel so that one of the sections can be turned relative to the other within the barrel, and means engaging the other section whereby the same is prevented from turning but is free to slide in the barrel, the said means limiting the turning movement of the first section, said sections having openings adapted to be brought in register by the turning movement of the section whereby the two portions of the barrel to each side of the plunger can be brought into communication.

2. In a grease gun of the class described, a barrel having a nozzle at one end, a key within on the lateral surface of the barrel Copies of this patent may be obtained for five cents each, by addressing the extending substantially through the entire length thereof, a the key so that it is free to slide within the barrel but prevented from turning therein, a piston rod projecting through the other end of the barrel and mounted to turn in the plunger section but prevented from longitudinal movement relative thereto, and a secondplunger section adjacent the first constrained to turn when the rod is turned, said sections having sectorial openings adapted to register when the rod is turned, said second plunger section having means engagin the key whereby the turning movement 0 the same is limited within the barrel and whereby the in the plunger sections is obtained.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
